Other Parts Discussed in Thread: OPA1633, OPA1622
Tool/software:
The circuit of OPA1632 is as shown in the attached schematic.
Right now, we have mounted only the first stage, U29 and its circuit. The capacitors C94 to C97 are removed…

Hi,
I'm hoping to continue the conversation from this previous thread here: https://e2e.ti.com/support/audio-group/audio/f/audio-forum/1421389/opa1622-en-shutdown-not-working
Does your team have recommendations
…Tool/software:
I am unable to find a dimensioned package drawing fore this device. The package name is VSON (DRC). I have checked on your website and the datasheet obviously.
Can you please help.

Hi,
I am making a studio headphone amplifier product based on the AK4499EX DAC (as discussed in a linked post). I would like more output power than a single OPA1622 can provide (300mA current would be ideal, even at…

Hi Experts,
Good day!
I'm looking for the thermal resistance information for the p/n below. No information in the datasheet can you share with us the thermal resistance and theta-JC of the device?
Hi team,
I downloaded the OPA1622 model on TI's website and used TINA TI to simulate the phase margin at different capacitive loads and found the simulation results to be inconsistent with the datasheet curve.
According to the…
Hello,
the typical EN pin input current for +25°C is given in the datasheet with 1.5 uA. Please specify the maximum input current considering the temperature range -40..125 °C.
Is the input current caused by a pull-up or a…
Hi Sir
Would you mind introduce a OP amplifier or DAC for me?
I have a design application for the MIC (MEMS) differential input to single-ended output, and I would like have a tiny package for it,
actually, I have…
I connected the 8th pin (EN) of the OPA1622 to V+ (+12V), the 3rd pin (GND) to V- (-12V) instead of GND, and connected the other pins as specified and continued to use them.
If so, what kind of failures and effects are possible?
…I connected pin 8 (EN) of OPA1622 to V+ (+12V), pin 3 (GND) to V- (-12V) instead of GND, and connected the other pins as specified and continued to use them.
If so, what are the possible inconveniences?
Testing an opa1622evm and powered it with 2x 13v batteries. I then connected the balanced output of a topping e70 dac to it and with no load the evm measured 4.8 vrms in and…
Hello All!
I'm experiencing a very odd behavior when trying to use the enable pin feature of the OPA1622 in the clipper circuit below:
As can be seen above, I'm setting the GND pin to -9V in order to reference the enable signal…
Hello All,
I've received a simple unity gain board that I designed and noticed a very odd behavior: when shorting the OPA1622 enable pin to ground, the output is clipped between -1.4V and +1.6V.
It was my understanding that when…
